collectd failing to dispatch to 'write' with 10.04 clients sending through the network plugin

[Joe McDonagh]

Binary package hint: collectd

Description: Ubuntu 10.04.1 LTS
Release: 10.04

collectd:
  Installed: 4.8.2-1
  Candidate: 4.8.2-1
  Version table:
 *** 4.8.2-1 0
        500 http://aptproxy/ubuntu/ lucid/universe Packages

I expect that collectd on new 10.04 nodes will send the statistics to the master collectd server without issue, just as it did with 8.04 LTS nodes.

Instead, there are tons of errors like this on the main collectd server:
14101: #-#-#T#:#:#.#-#:# syslog collectd[#]: Filter subsystem: Built-in target `write': Dispatching value to all write plugins failed with status -#.

That number (14101) is how many of these errors are reported *in one day*. On the nodes causing this (I Know the 10.04 clients cause it because the errors stop when I stop collectd on the nodes) I get hundreds of errors similar to this:

36: #-#-#T#:#:#.#-#:# syslog collectd[#]: uc_update: Value too old: name = puppet/interface/if_errors-eth#; value time = #; last cache update = #;

I want to make clear that 8.04 nodes work fine sending to this box. There are no errors reported in that case. It's only when 10.04 nodes send to it.
